MANUFACTURE OF CYLINDRICAL PHONOGRAPH RECORD-BLANKS.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed October 13, 1906. Serial No. 838;72'7.

T 0 all rah/0771 it may concern:

Be it known that I, V ARIAN M. HARRIS, a

citizen of the United States of America, and

a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements-in the Mannfacture of Cylindrical Phonograph Record- Blanks, of which the following isa specification.

This invention relates to means for forming cylindrical phonograph record blanks from sheets of celluloid, and has for its object to provide a simple and eflicient structural arrangement and combination of parts whereby the sheet of material bent into a cylindrical form is securely held and united by a longitudinally extending cemented seam to form a cylindrical blank equal in all respects to the drawn tubes or cylinders heretofore used in the manufacture of phonograph records, all as will hereinafter more fully appear.

In the accompanying drawings :Figure 1 is a longitudinal sectional elevation, on line as-:r, Fig. 3, of an apparatus embodying the present invention, and showing the parts in the position in which the carriage has completed an active stroke. Fig. 2 is a similar view showing the parts in the position for the commencement of an active stroke. Fig. 3 is an enlarged end elevation.

Similar numerals of reference indicate like parts in the different viewss Referring to the drawings, 1 represents a stationary slideway of any usual construction, and provided with suitable feet by which it is supported in a horizontal position upon a work bench or table.

2 are a plurality of saddle pieces secured in fixed relation to the slideway 1, and adapted to support the cylindrical work holder in proper position in the apparatus.

3 is the cylindrical work holder above referred to, and consisting of a cylindrical shell of metal, or other equivalent rigid material, slitted along its length to form the longitudinal opening or gap 4 in the wall of the holder as shown.

5 are ears upon the opposed edges of the gap 4, through which pass adj listing screws 6, by which an adjustment in the diameter of the holder can be effected as required in the actual and continued use of the apparatus.

on, and which is bent into a cylindrical form and inserted into the interior of the cylindrical holder 3, with the meeting edges and seam formed. thereby, located at the under side of the blankcelluloid cylinder so formed, and as shown more particularly in Fig. 3.

8 is a carriage sliding longitudinally on the slideway 1, and carrying a supply tank 9 in which is contained a supply of the cementing fluid used in the practical operation of the apparatus, and which fluid will. usually consist of a cellulose product dissolved in ether.

10 is a fountain pen pivota-lly supported on the carriage S, and having one end connected by a flexible tube 11, with the supply tank 9, while its other end is of an elon gated form and ends in a capillary discharge point 12 through which the cementing fluid flows, as said point moves in contact with the work.

13 is a depending operating arm rigidly connected tothe fountain pen 10, aforesaid.

14 and 15 are stationary stops arranged near the limit of the longitudinal travel of the carriage 9, in each direction, and which are adapted to alternately contact with the arm 13 to raise the discharge point 12 from the work, at the ending of its active stroke, and in like manner depress said discharge point at the ending of its inactive stroke and previous to the beginning of the active stroke; such operations taking place in an automatic manner during a continued operation of the apparatus. 3

The operation of the apparatus is as follows 2-A sheet of celluloid of the proper dimensions is bent into a cylindrical form and inserted in the interior of the cylindrical work holder 3, which is adjusted to the required diameter by the adjusting screws 6. The work holder is then placed in position on the saddle pieces 2, with the seam of the celluloid cylinder located at the lowermost point in the height of said cylinder as shown. The operator now moves the carriage 8 to bring the discharge point 12 of the fountain pen 10 to the rear end of the interior of the work and work holder, as illustrated in Fig. 2, and as such position is reached the stop 15 contacts with the arm 13 to automatically depress the discharge point 12 to an operative position. A return movement is now imparted to the carriage and the discharge point 12 is drawn along the longitudinal seam of the celluloid cylinder 7 to deposit the cementing solution; with the ending of such active or return stroke of the carriage, the stop 14 contacts with the arm 13 to automatically raise the discharge point 12 into its normal inoperative position. The work holder with its contained cylinder of celluloid, is now re moved from the apparatus and stacked away to dry out, and 1S replaced by a succeeding holder and its contained sheet of celluloid, the system requiring a large number of counterpart Work holders in the attainment of rapid and perfect work.

Having thus fully described my said inven tion, what I claim as new and desire to secure by Letters Patent, is

1. In an apparatus for forming sheet celluloid into cylindrical phonograph record blanks, the combination of a cylindrical work holder adapted to maintain a sheet of celluloid in a cylindrical form, means for supporting the work holder in a horizontal position, a slideway arranged longitudinal to the work holder, a carriage moving on said slide way, and a fountain pen carried by said carriage.

2. In an apparatus for forming sheet celluloid into cylindrical phonograph record blanks, the combination of a longitudinally slotted cylindrical work holder adapted to maintain a sheet of celluloid in a cylindrical form, means for effecting a change in the diameter of said work holder, means for supporting the work holder in a horizontal position, a slideway arranged longitudinal to the work holder, a carriage moving on said slideway, and a fountain pen carried by said carriage.

3. In an apparatus for forming sheet celluloid into cylindrical phonograph record blanks, the combination of cylindrical work holder adapted to maintain a sheet of I celluloid in a cylindrical form, stationary saddle pieces for supporting the work holder in a horizontal position, a slideway arranged longitudinal to the work holder, a carriage movssesae ing on said slideway, and a fountain pen car ried by said carriage.

4. In an apparatus for forming sheet celluloid into cyllndrical phonograph record blanks, the combination of a longitudinally slotted cylindrical work holder adapted to maintain a sheet of celluloid in a cylindrical form, stationary saddle pieces for supporting the work holder in a horizontal position, a slideway arranged longitudinal to the work holder, a carriage moving on said slideway, and a fountain pen carried by said carriage.

5. In an apparatus for forming sheet celluloid into cylindrical phonograph record blanks, the combination of a cylindrical work holder adapted to maintain a sheet of celluloid in a cylindrical form, means for supporting the work holder in a horizontal posi tion, a slideway arranged longitudinal to the work holder, a carriage moving on. said slideway, a supply tank on said carriage, a pivoted fountain pen carried by said carriage and connected with said tank, and means for tilting said pen near the ends of its travel.

6. In an apparatus for forming sheet celluloid into cylindrical phonograph record blanks, the combination of a longitudinallv slotted cylindrical work holder adapted to maintain a sheet of celluloid in a cylimlriral form, means for effecting a change in the diameter of said work holder, means for supporting the Work holder in a horizontal position, a slideway arranged longitudinal to the work holder, a carriage moving on said slideway, a supply tank on said carriage, a pivoted fountain pen carried by said carriage and connected with said tank, and means for tilting said pen near the ends of its travel.
